Stationary Waves/Standing Waves

Front

How are standing waves created?

Back

Two identical waves move through each other in opposite directions

Front

The moving black dot is called:

Back

an anti-node

Front

The stationary dot is called:

Back

node

Front

Back

A C E

Front

The diagram shows the standing wave pattern of a vibrating string which is fixed at ends X and Y.
Which one of these statements is true? Options: P to R is one wavelength., At R the string will move up., The lowest frequency for this string is one third of its current value., The kinetic energy of the string is at its maximum value.

Back

The lowest frequency for this string is one third of its current value.

Front

A receiver R is moved from S (a reflector) towards T (a transmitter). The intensity changes as in the diagram. Which of the following statements is correct?

Back

The frequency of the microwaves is 2.5 GHz.

Front

A standing wave:

Back

stores energy.

Front

What are the boundary conditions for these standing waves? Options: Anti-nodes at each end., The surface of the string is smooth., The string is free at both ends., There is a node at each end.

Back

There is a node at each end.

Front

Wavelengths that cannot produce a standing wave in a 1 m rope fixed at both ends: 2 m, 1/3 m, 1/4 m, 3 m.

Back

3 m

Front

Standing waves created in strings, pipes, and closed pipes have specific wavelengths that fit into the length of those instruments.

Back

True
